You see stars if you have been sitting still or laying down and then stand up rapidly because in a state of rest your blood pressure is low and your heart needs to pump blood at a higher pressure during your sudden state of exertion for oxygen-filled blood to reach your brain. Generally, your heart will quickly adjust and you will not see stars or feel dizzy for longer than a few seconds. You can keep this from happening by standing up more gradually.
If you always "see stars" when you stand up or ever feel like you're going to pass out, you should talk to your doctor about it.
When you stand up too quickly, your blood pressure changes suddenly, causing reduced blood flow to your brain. This temporary decrease in blood flow can lead to a brief interruption in the function of the cells in your visual system, resulting in the sensation of seeing stars.
